An early version of the new Form Autofill feature is ready for testing by early adopters with U.S. addresses and websites using Firefox Nightly on desktop. Form Autofill helps you fill out addresses in online forms. You can give the work-in-progress a try and watch it improve over time but keep in mind there are many more months of work left to go.

mozscreenshots is now running in automation on Nightlies and on-demand for try pushes, making it much easier to capture images to detect UI regressions and make it easier to review how the UI looks. Comparing the captured images to a reference/base version can now be done via a web interface which means the images don’t need to be downloaded for review.

There is now an easy way to review Firefox user interface changes without even installing the new version. "How is that possible?" you might ask. We have a collection of hundreds of screenshots of the new Firefox in various different configurations (affecting features such as tabs, toolbars, themes, customization mode, and the new menu) that are ready for you to review.
